"A senior OpenBSD developer has complained on a mailing list that upstream vendors of free and open source software are adding in changes without any thought of whether downstream users could adapt to the change. Marc Espie said this would hurt smaller players by not allowing them to keep up with the changes. Basically what is happening is that numerous changes are being made to Linux and smaller projects like OpenBSD cannot keep up with the changes. And, according to Espie, not all these changes are strictly necessary."
